SYSTEM09.dbf file corrupted in R12.1.1 fresh install on Linux x86_64

Thankfully those corruption are not data corruption (does not belong to any extents/segments) hence will not affect your installation and database startup. Might be this was the reason that Oracle could not capture this issue before it releases to the customer.

User will identify this corruption only when they starts to backup using RMAN or validates datafile using RMAN. RMAN will fail with below error message,

ORA-19566: exceeded limit of 0 corrupt blocks for file /DBF_LOC/system09.dbf

On verifying the datafile using dbv, there will be around 20000+ corrupted blocks in system09.dbf,
